Description

QUINAZOLINE-BASED COMPOUND, COMPOSITION, AND APPLICATION OF
QUINAZOLINE-BASED COMPOUND
FIELD OF THE INVENTION
[0001] The present disclosure belongs to the field of pharmaceutical technology and relates to quinazoline-based compounds, compositions and applications thereof.
BACKGROUND OF THE INVENTION
[0002] Epidermal growth factor receptor (ErbB) tyrosine kinases can regulate cell proliferation, migration, differentiation, apoptosis, and cell movement through multiple pathways. ErbB family members, as well as some of their ligands, are commonly overexpressed, amplified, or mutated in many forms of malignancy, making them important therapeutic targets. This family of protein kinases includes ErbB1/EGFR/HER1, ErbB2/HER2, ErbB3/HER3, and ErbB4/HER4, of which EGFR and HER2 are important targets for the development of drugs for non-small cell lung cancer and breast cancer (Dienstmann R., et. al., (2001) Personalizing Therapy with Targeted Agents in Non-Small Cell Lung Cancer.
ONCOTARGET. 2(3), 165.; Mitri Z., et. al. (2012) The HER2 Receptor in Breast Cancer:
Pathophysiology, Clinical Use, and New Advances in Therapy., Chemotherapy Research &
Practice., Volum 2012 (23), 743193.). Currently, several generations of EGFR
and HER2 kinase inhibitors are also on the market.
[0003] However, the expression of EGFR and HER2 is not stable, and frequent amplification and rearrangement of genes occur, which changes the antigenic phenotype on the surface of tumor cells. The efficacy of the existing targeted drugs on different mutations of EGFR and HER2 varies greatly, wherein the inhibitory ability against 1n520 is the weakest, causing the 1n520 mutation to become a drug-resistant mutation for which the current multiple generations of targeted drugs are almost ineffective. The exon 20 mutations of EGFR and HER2 genes occur in similar positions, but there are many types of EGFR exon 20 insertion mutations, of which 122 kinds have been found; in contrast, there are fewer types of HER2 gene exon 20 insertion mutations, the most common being the A775_G776insYVMA site, which accounts for nearly 70% of the total number of mutations. Statistics also show that about 3% of NSCLC

patients carry HER2 mutations, wherein about 90% are patients with exon 20 mutant types of the HER2 gene. For these EGFR/HER2 exon 20 mutation patients, the efficacy of existing targeted TKI drugs is very limited.
[0004] Meanwhile, there are also a small number of research projects targeting the EGFR/HER2 In520 mutation. Poziotinib is a broad-spectrum HER inhibitor developed by Hanmi. Clinical data show that Poziotinib also has certain effects on exon 20 mutations of EGFR/HER2, but has a high rate of adverse reactions. At the same time, the marketed pyrotinib is also undergoing clinical research on related exon 20 mutations.
[0005] In addition, in recent years, EGFRvl I I, a class of mutants of the epidermal growth factor receptor EGFR expressed only on the surface of tumor cells rather than on the surface of cells of normal tissues, has also been identified, and is also a very common EGFR mutant. In contrast to the intact structure of EGFR, exons 2-7 encoding the extracellular ligand-binding region of EGFRvIl I are deleted, resulting in an 801-base pair deletion that allows exons 1 and 8 to be linked and a new glycine to be generated at this binding site, causing the deletion of amino acids 6 to 273, and thus a loss of the ability to bind to the ligand EGF. EGFRvl II, in the absence of ligand binding, structurally activates tyrosine kinases in an unregulated manner by dimerization and autophosphorylation, inducing downstream signaling and stimulating tumor cell proliferation. Therefore, the development of new molecularly targeted therapeutics against EGFRvl I I would provide more effective and cost-effective treatment options for tumor patients, and there is a huge unmet clinical need.
[0006] From the perspective of a chemical structure, many TKI drugs on the market, as well as poziotinib and pyrotinib as mentioned above, are all derived from the structure of quinazoline or quinoline. As shown in the figure below, when constructing a TKI inhibitor through quinazoline or quinoline, an aniline-based group is usually introduced at the 4-position, and substitutions are made at the 6-position and the 7-position at the same time. The pyrotinib, neratinib, and poziotinib shown in the figure below are all substituted with an alkoxy group at the 7-position, and have also a substituent at the 6-position. However, there are few attempts to construct TKI inhibitors by substitution at the 5-position. In this application, a series of quinazoline compounds have been synthesized by introducing a substituent at the 5-position and removing a substituent at the 7-position, which exhibit excellent inhibitory activity against HER2 and exon 20 mutations thereof, and are expected to be used in the treatment of HER2 exon 20 mutations.
[0007] It is worth mentioning that none of the currently marketed small molecule HER2 inhibitors can effectively penetrate the blood-brain barrier, and brain metastasis occurs in about 50% of HER2-positive breast cancer patients. In view of the fact that some compounds of the present application can effectively penetrate the blood-brain barrier and have an extremely strong inhibitory effect on HER2-positive tumors, the compounds of the present application are also expected to be used in the treatment of patients with brain metastasis from HER2-positive breast cancer.

[0087] The term "deuterated derivative" refers to a derivative obtained by deuteration of optionally one or more hydrogen atoms in the compound of this application.
[0088] The term "each independently" means that where more than one substituents are selected from a number of possible substituents, those substituents may be the same or different.
[0089] It is clear that the compound of formula I, or stereisomer, crystalline form or prodrug thereof, and pharmaceutically acceptable salt thereof, may exist in a solvated or non-solvated form. For example, the solvated form can be a water-soluble form. The present disclosure includes all the solvated and non-solvated forms.
[0090] In this disclosure, the term "isomer" refers to different compounds having the same molecular formula, and may include various isomeric forms such as stereoisomers and tautomers. "Stereoisomers" are isomers that differ only in the arrangement of their atoms in space. Some compounds described herein contain one or more asymmetric centers and thus can give rise to enantiomers, diastereomers, and other stereoisomeric forms which can be defined as (R)- or (S)-based on absolute stereochemistry. The chemical entities, pharmaceutical compositions, and methods disclosed herein are intended to include all of these possible isomers, including racemic mixtures, optically pure forms, and intervenient mixtures between them. Optically active (R)- and (S)-isomers can be prepared using chiral synthons or chiral reagents or resolved using conventional techniques. The optical activity of a compound can be analyzed by any suitable method, including but not limited to chiral chromatography and polarimetry, and the degree of dominance of one stereoisomer over other isomers can be determined.
[0091] Individual stereoisomers (or isomers-enriched mixtures) of a compound of this disclosure may be resolved using methods known to those skilled in the art.
For example, such resolution may be carried out by: (1) formation of diastereoisomeric salts, complexes or other derivatives; (2) selective reaction with a stereoisomer-specific reagent, for example by enzymatic oxidation or reduction; or (3) gas-liquid or liquid chromatography in a chiral environment, for example, on a chiral support such as silica bound with chiral ligands or in the presence of a chiral solvent. The skilled artisan will appreciate that where the desired stereoisomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired form.
Alternatively, specific stereoisomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer to the other by asymmetric transformation.
[0092] When a compound described herein contains an olefinic double bond, it means that the compound includes various cis- or trans-isomers, unless otherwise stated.
[0093] "Tautomers" are structurally different isomers that are interconvertible to each other through tautomerization. "Tautomerization" is a form of isomerization and includes a prototropic change or proton transfer tautomerization, which can be considered as a subset of acid-base chemistry. "prototropic change tautomerization" or "proton transfer tautomerization"
involves the migration of a proton accompanied by a bond-level transformation, which is often exchange of a single bond with an adjacent double bond. When tautomerization is possible (for example, in solution), tautomers can reach chemical equilibrium. An example of tautomerization is keto-enol tautomerization.
[0094] The compound of the present disclosure as an active ingredient, and the method of preparing the same, are both included in the present disclosure. Moreover, the crystalline form of some of the compounds may exist as polymorphs, and such forms may also be included in the present disclosure. Additionally, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents, and such solvates are also included within the scope of the disclosure.
[0095] The compounds of the disclosure may be used in the free form for treatment or, when appropriate, in the form of a pharmaceutically acceptable salt or other derivative for treatment.
As used herein, the term "pharmaceutically acceptable salt" refers to organic and inorganic salts of the compounds of the present disclosure which are suitable for use in human and lower animals without undue toxicity, irritation, allergic response, etc., and have reasonable benefit/risk ratio. Pharmaceutically acceptable salts of amines, carboxylic acids, phosphonates, and other types of compounds are well known in the art. The salt can be formed by reacting a compound of the disclosure with a suitable free base or acid, including, but not limited to, inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, perchloric acid or organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, malonic acid. Or the salts may be obtained by methods well known in the art, such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, besylate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, dig luconate, lauryl sulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerol phosphate, glyconate, hemisulfate, hexanoate, hydroiodide, 2-hydroxyethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, ma leate, mesylate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, palmitate, pamoate, pectate, persulphate, per-3-phenylpropionate, phosphate, picrate, propionate, stearate, sulfate, thiocyanate, p-toluenesulfonate, undecanoate, and the like. Representative alkali or alkaline earth metal salts include salts of sodium, lithium, potassium, calcium, magnesium, and the like.
Other pharmaceutically acceptable salts include suitable non-toxic salts of ammonium, quaternary ammonium, and amine cations formed from halides, hydroxides, carboxylates, sulfates, phosphates, nitrates, lower alkyl sulfonates and aryl sulfonates.
[0096] Further, the term "prodrug" as used herein means that a compound can be converted into the compound of the present disclosure in vivo. Such transformation is affected by hydrolysis of the prodrug in the blood or enzymatic conversion to the parent compound in the blood or tissue.
[0097] Pharmaceutical compositions of this disclosure comprise the compound described herein or a pharmaceutically acceptable salt thereof; an additional active agent selected from a kinase inhibitory agent (small molecule, polypeptide, antibody, etc.), an immunosuppressant, an anticancer agent, an anti-viral agent, anti-inflammatory agent, antifungal agent, antibiotic, and an anti-vascular hyper proliferation compound; and any pharmaceutically acceptable carrier, adjuvant or excipient.
[0098] The compounds of the present disclosure may be used alone or in combination with one or more of other compounds of the present disclosure or with one or more of other agents.
When administered in combination, the therapeutic agents can be formulated for simultaneous or sequential administration at different times, or the therapeutic agents can be administered as a single composition. By "combination therapy", it refers to the use of a compound of the present disclosure in combination with another agent, in a manner whereby each agent is co-administered simultaneously or administered sequentially, in either case, for the purpose of achieving the optimal effect of drugs. Co-administration includes dosage form for simultaneous delivery, as well as separate dosage forms for each compound.
Thus, administration of the compounds of the disclosure can be combined with other therapies known in the art, for example, radiation therapy or cytostatic agents, cytotoxic agents, other anticancer agents, and the like as used in the treatment of cancer, in order to improve the symptoms of cancer. The administration sequence is not limited in the present disclosure.
The compounds of the present disclosure may be administered before, simultaneously, or after other anticancer or cytotoxic agents.
[0099] To prepare the pharmaceutical ingredient of the present disclosure, one or more compounds of Formula (I) or salts thereof as an active ingredient can be intimately mixed with a pharmaceutical carrier, which is carried out according to conventional pharmaceutical formulation techniques. The carrier can be used in a wide variety of forms depending on the form of preparation which is designed for different modes of administration (for example, oral or parenteral administration). Suitable pharmaceutically acceptable carriers are well known in the art. A description of some of these pharmaceutically acceptable carriers can be found in the Handbook of Pharmaceutical Excipients, published jointly by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.

[00264] Preparation of the assay compound: an appropriate weight of the compound to be assayed was weighed, and completely dissolved in an appropriate volume of veihcle (DMSO).
The mixture was vortexed or sonicated. Then an appropriate amount of Solutol was added and mixed well. Finally, sterilized drinking water was added and the mixture was mixed by stirring or vortexing to obtain a homogeneous solution or suspension.
[00265] Method: All the assays were authorized and agreed by the Animal Welfare Committee. Ba/F3 ERBB2 A775_G776insYVMA in a logarithmic growth period was inoculated subcutaneously into the right back of immunodeficient nude mice (BALB/c nude, female, 6-7 weeks of age, body weight 18 2g) with 4x106 cells/rat. After the tumor grew to 150-200 mm3, the animals were randomly divided into a treatment group and a control group.
For the treatment group, a solution of each assay compound was given, and for the control group, a vehicle solution without the assay compound was given. Both of the treatment group and the control group were administered once a day for about 2 weeks. The dose of each assay article was 30 mg/kg (in terms of effective compound concentration), and the assay compounds were all prepared freshly for use. During the assay, the diameter of loaded tumors was measured twice a week, and the mice were weighed at the same time. The tumor volume (TV) was calculated by the formula: TV = 1/2 x a x b2, where a and b denote length and width, respectively. Relative tumor volume (RTV) was calculated based on the measured results by the formula: RTV = Vt/VO, where VO is the tumor volume measured at grouping and administration and Vt is the tumor volume at each measurement. The evaluation index of antitumor activity was the relative tumor proliferation rate T/C (%) calculated by the formula:
T/C (%) = (TRTV / CRTV) x 100 %, TRTV: RTV of the administration group; CRTV:
RTV of the control group. T and C denote the average tumor volume at a certain time point in the administration group and the control group, respectively.
[00266] The assay results are shown in Table 14 below and Fl Gs. 1-9. As shown in the Table and Figures, Neratinib and Pyrotinib have certain tumor inhibitory effects at a dose of 30 mg/kg, with T/C values of 45.9% and 38.3%, respectively, at day 14. The compounds of Example 4, Example 8, Example 9, Example 11, Example 24, Example 29, and Example 33 of the present application have significant tumor inhibitory effects at a dose of 30 mg/kg, wherein the T/C values of the compounds of Example 4 and Example 24 are 2.6%
and 12.4%

at day 14, respectively, and the TIC values of the compounds of Example 8, Example 9, and Example 11 are 5.83%, 3.85%, and 5.71% at day 15, respectively, and the TIC
values of the compounds of Example 29 and Example 33 are 18.7% and 12.4% at day 11, respectively.
Combined with the above results of the assay of the proliferative activity of Ba/F3 HER2 A775-G776sYAMA cells, it can be seen that the compounds of the present application not only have anti-tumor cell proliferation activity in vitro against the exon 20 insertion mutation of HER2 (HER2 A775_G776insYVMA) that is superior to that of Pyrotinib and Neratinib, but also show far superior antitumor activity to Neratinib and Pyrotinib in nude mouse tumor-bearing model of Ba/F3 ERBB2 A775_G776insYVMA. All assayed compounds achieve significant tumor shrinkage, while tumors in the Neratinib and Pyrotinib groups still remain significant growth at the same dose (30 mg/kg).
